What type of access device is commonly used for long-term intravenous therapy?

A PICC line, or Peripherally Inserted Central Catheter, is commonly used for long-term intravenous therapy due to its ability to remain in place for extended periods, generally weeks to months, while providing a reliable route for administering medications, fluids, or nutrition directly into the bloodstream. This type of catheter is inserted into a peripheral vein, usually in the upper arm, and advanced towards the heart.

Its design makes it especially beneficial for patients requiring prolonged treatments, such as those undergoing chemotherapy or long-term antibiotic therapy, as it minimizes the discomfort and complications associated with frequent needle sticks for intravenous access.

While other options like dialysis grafts and fistulas are also types of access devices, they are specifically designed for patients undergoing dialysis rather than general intravenous therapy. An IVC filter, on the other hand, is intended for preventing pulmonary embolism and is not used for intravenous therapy. Thus, the PICC line stands out as the most suitable device for long-term intravenous use.
